AI Technical Summary

Benefits of technology

This solution reduces drag, wear on seals, and maintenance needs, while maintaining the door flush with the mold line, thereby minimizing weight and operational stress on the aircraft.

Problems solved by technology

These types of operations may increase the load on the door.
Additionally, currently used doors may open outward in a manner that may increase the drag on the aircraft.
These currently used door systems may be subjected to high loading, flutter, fatigue, increased drag, and shock generation during supersonic weapons release because they may extend outside of the mold line of the vehicle body.
Further, these types of aircraft doors also may have complex heavy hinges.
These complex hinges may experience high amounts of stress and wear on aerodynamic edge seals.
Also, with the complexity of these doors, the amount of maintenance needed for the doors may take the aircraft out of service for periods longer than desired.
Additionally, the complexity and weight of the doors and hinges also may add to the weight of the aircraft, which may be undesirable.

Embodiment Construction

[0031]Referring more particularly to the drawings, embodiments of the disclosure may be described in the context of the aircraft manufacturing and service method 100 as shown in FIG. 1 and aircraft 200 as shown in FIG. 2. Turning first to FIG. 1, a diagram illustrating an aircraft manufacturing and service method is depicted in accordance with an advantageous embodiment. During pre-production, exemplary aircraft manufacturing and service method 100 may include specification and design 102 of aircraft 200 in FIG. 2 and material procurement 104.

[0032]During production, component and subassembly manufacturing 106 and system integration 108 of aircraft 200 in FIG. 2 takes place. Thereafter, aircraft 200 in FIG. 2 may go through certification and delivery 110 in order to be placed in service 112. While in service by a customer, aircraft 200 in FIG. 2 is scheduled for routine maintenance and service 114, which may include modification, reconfiguration, refurbishment, and other maintenance...

Abstract

A method and apparatus comprising a frame and a door. The door may be moveably connected to the frame. The door may be capable of being rotated in the frame between a closed position and an open position to provide access to an opening of a vehicle body without moving the door outside of a mold line of the vehicle body.

Description

BACKGROUND INFORMATION[0001]1. Field[0002]The present disclosure relates generally to aircraft and, in particular, to a method and apparatus for providing access to an aircraft. Still more particularly, the present disclosure provides a method and apparatus for providing access to an aircraft using a door.[0003]2. Background[0004]An aircraft door may provide access to an interior of an aircraft. A door for an aircraft may typically have an outer skin that may conform to the surrounding outside mold line of the body of the aircraft. The outer surface of the aircraft door may form a substantially uninterrupted surface during flight which may not produce additional drag while sealing the door opening of the fuselage of the aircraft.[0005]In some cases, an aircraft door may be opened during flight for various operations. These operations may include, for example, without limitation, deploying landing gear, deploying weapons, opening auxiliary air intakes, deploying cargo, and / or other s...
